body
DEPARTMENT: Department of Public Works
SUBMITTED BY: Richard Dublinski, Director
BACKGROUND:
In June 2019, City Council awarded Contract 19-060 to Hoerr Construction Inc. to clean, televise and install cured-in-place-pipelining (CIPP) in storm sewer segments. The term of the contract was from date of award to December 5, 2019, with two, one-year options to extend. In March 2020, City Council awarded the first option year. The term of the first option year is from April 1, 2020 to March 31, 2021, with one, one-year option available. The purpose of this contract is to rehabilitate storm sewer pipe ranging from 8 inches to 30 inches in diameter, which will improve the conductive capacity and extend the useful lifespan of the existing storm sewer system.
During the first option year, Hoerr Construction completed the rehabilitation of approximately 11,500 feet of storm sewer ranging from 8 inches to 36 inches in diameter. The work included cleaning, televising and sealing the sewer with cured-in-place-pipelining. In 2020, work was completed in grids 114 and 129 (West Highlands) as well as single run repair sections in other grids.
DISCUSSION:
This change order is requested to line the 30” culvert at Royce Road and Barkdoll Road. When the line was televised it was discovered that the bottom of the pipe had eroded, causing a dip in Royce Road from the ground sinking under the road. There was a need to remedy this quickly so that there would not be a large sinkhole that would require shutting down Royce Road.
The amount of this change order exceeds the original contract amount by $6,000 and increases the original contract expiration date by zero days.
I, Fred Girard, of the Department of Public Works certify that this work is necessary for successful completion of this contract. I further certify that the circumstances said to necessitate the change in performance were not reasonably foreseeable at the time the contract was signed, or the change is germane to the original contract as signed, or the change order is in the best interest of the city and authorized by law.
This contract was approved with contingency in the amount of 3% ($18,000) of the original contract value. Staff requests the use of contingency funds for the change order. A summary of the award and contingency information is provided in the tables below.
